•254 BIRDH OF ILLINOIS. 



nntl oxliibitinp a slight resemblance to ('. luiiHloni. The upper parts 

 lire less varied. 



"Specimens from the Tiir Wist have the bill more slender, the 

 reddish of the back considiraMy paler, the dark mnrkin^s of the 

 l.aik restricted, the light stripe un the head with scarcely any yel- 

 low, a decided spot in front of the eye quite yellow, and little or no 

 uchraceous on the breast. 



"The young bird, with streaked jugulum, may be most readily 

 disthiguished from C. heitslowi by the grayer plumage without any 

 shade of chestnut or greenish yellow, the sparseness of streaks on 

 the side, the absence of the two mandibular dusky stripes, and the 

 broad dusky centres of the middle tail-feathers." (Hist. S. Am. B.) 



This little bird is abundant in all cultivated portions of the State, 

 as well as on the open prairie. To the rural population it is known 

 as the "Grass-bird," "Ground-bird," or "Grasshopper-bird," the lat- 

 ter appellation being derived from its grasshopper-hke song, which 

 it utters from the end of a fence-stake, the top of a tall weed-stalk, 

 or as it sits upon the summit of a haycock in the meadow. The 

 gi-eater portion of its time is passed in the grass, in which it runs 

 from the intruder, unseen, like a mouse ; or, if pressed too closely, 

 rises suddenly and flies a greater or less distance in a zigzag man- 

 ner, exceedingly provoking to the collector, who finds it a difficult 

 mark to liit.
